Even if the UV light works, there is no way for it to reach the entire coil.

It may not sterilize a house, as the air typically only gets turned over 2-3 times an hour.
It does however work. Even whizzing past the UV light at high speed. Also, the light is on the coil itself, sanitizing surfaces. I'm sorry that you don't believe it. Don't take my word for it, look it up yourself. Independent, lab tested and proven results. It does inactivate organics, even blowing past at speed. I have no dog in this fight, I don't sell, install or otherwise care what someone believes or doesn't believe. I do believe that that true is true. They actually work, at least quality systems by reputable companies. I don't have one in my house, I'm not justifying a purchase either. I'm just a data nerd and the data is in. It works.
